Two close-coiled helical springs are arranged, parallel (one inside the other) about the same longitudinal axis. Both springs have the same number of coils and same overall length, but the mean coil diameter of the outer spring, which is made of steel wire, is twice that of the inner spring, which is made of bronze wire. The springs are designed to act together when a tensile force is applied, so that both suffer the same change in length and each carries half the force. Determine the ratio of the wire diameters, and the retio of the stresses produced in the wires, if Esteel = 2 x Ebronze,

Under some circumstances, when two parallel springswith constants k1 and k2 support a single mass, theeffective spring constant of the system is given byk 4k1k2/(k1 + k2). A mass weighing 20 pounds stretchesone spring 6 inches and another spring 2 inches. Thesprings are first attached to a common rigid supportand then to a metal plate. As the figure illustrates(see image), the mass is attached to the center of the plate in the distributiondouble spring. Determine the constant of theeffective spring for this system. find the equationof motion if the mass is initially released fromequilibrium position with downward speed of2 ft/sec.

1. In lecture I focused on a horizontal mass-spring system so we could ignore gravity, but in practice it's much easier to build a vertical mass-spring system. In the figure below, we can see a suspended spring with spring constant k both before and after a mass m is hooked to it. Y Yo yo is the equilibrium height of the spring (without the mass) and in the figure y = 0 is set at the ground. a) Using the coordinate system in the figure, show that Newton's second law for the hanging mass-spring system leads to the following differential equation: d²y dt² k (y - Yo) - g m b) Now define a new coordinate, y', related to y by a constant shift: y = y' + C, where C = constant. Show that if you choose the right value of C, Newton's second law is identical in form to a mass-spring system without gravity. What is the period of the system? c) Effectively, gravity just shifts the equilibrium position of the system, but the system still undergoes simple harmonic motion. What is the net force on the…

1. A helical compression spring is made of hard-drawn spring steel wire with a wire diameter d = 0.080 in and an outer coil diameter OD = 0.880 in. The ends are plain and ground, and there are 8 total coils. Determine the force F, required to close the spring, the spring constant k, the free length of this spring corresponding to n, = 1.2, and the pitch p.
